Abstract

La présente invention se rapporte à une installation hydraulique (Ih) comprenant, un moyen de commande pour inverser de manière répétitive, le sens de fonctionnement d'au moins un vérin hydraulique (V) à double effet et à mouvement rectiligne pour déplacer un accessoire dans un mouvement de va-et-vient. Selon l'invention, le moyen de commande (100) comprend quatre valves hydrauliques (Ev) 2/2 et dont une paire (Ev1, Ev4) est raccordée en montage parallèle, par l'intermédiaire d'un premier circuit hydraulique (1), à la chambre amont (Cm) dudit vérin et dont l'autre paire (Ev2, Ev3) est raccordée en montage parallèle, par l'intermédiaire d'un second circuit hydraulique (2), à la chambre aval (Ca) dudit vérin ou inversement. L'installation de l'invention avec son moyen de commande est capable de faire fonctionner au moins un vérin hydraulique à double effet suivant un mouvement rectiligne alternatif, avec une cadence de fonctionnement relativement élevée. Les pics de surpression dans les circuits de l'installation sont considérablement réduits. Un procédé pour inverser de manière répétitive, le sens de fonctionnement d'au moins un vérin hydraulique (V) à double effet et à mouvement rectiligne, fait partie également de l'invention.
